"We are also getting some assemblages from Dennis' own collection--he retained a lot of his early work," Deitch said.

It helps, Deitch noted, that many of Hopper's works--including his famous 1961 "Double Standard" image (pictured)--are photographs done in editions, so there are multiple examples in existence.

It also helps, one could add, that Hopper was never an art-market darling whose work was snapped up by all the big collectors and museums. MOCA, for instance, does not have a single example of his work in its permanent collection.
